Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh afternoon sun in hot climates; ensure adequate light indoors with supplemental grow lights if needed.
Care Requirements
Care Difficulty
very easyeasy
Sunlight
full sun
Rotate plants for even light exposure; use sheer curtains to filter intense sun; avoid placing in dark corners.
Watering
every 7–10 days, allowing soil to dry between waterings
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overhead watering.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (6.0–7.0).
Avoid heavy clay soils; use raised beds for better drainage; amend with organic matter.
Temperature
Warm temperatures (65–85°F/18–29°C); thrives in heat; sensitive to frost.
Avoid sudden temperature changes; protect from drafts; maintain consistent warmth.
Fertilizing
every 4–6 weeks during growing season
Fertilize sparingly to prevent leggy growth; flush soil occasionally to prevent salt buildup; stop fertilizing before flowering.
Propagation
Methods
Stem cuttings or seed; stem cuttings root easily in water or soil.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Place in medium.
- Keep moist and warm.
Best Time: Spring or early summer when growth is active.
Environment
Warm, humid conditions with indirect light.
Medium
Well-draining soil mix or water with occasional changes.
Hormone
Optional but can speed up rooting.
Timeline
Roots develop in 1–3 weeks; mature plant in 2–3 months.
Tools Needed
Pruning shears, rooting hormone (optional), small pots, water or soil medium.
Quick Tips
Use clean tools to prevent disease; keep cuttings out of direct sun; maintain consistent moisture.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Light pruning to maintain shape and encourage bushier growth; remove dead or damaged stems.
Tools
Pruning shears, sharp scissors.
Checklist
Use clean tools; prune dead or leggy growth; shape as desired.
Repotting Guide
Best Season
Spring, before the active growing season.
Pot Size
One size larger pot; ensure it has drainage holes.
Method
Remove plant gently; trim roots if needed; place in fresh soil with good drainage.
Suggestions
Repot if roots are crowded or growth slows; every 1–2 years for container plants.
Checklist
Choose appropriate pot size; use fresh soil; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wetting leaves.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or leaf drop in extreme cold or heat.
Cold Stress
Growth slows or halts; leaves may turn purple or brown; risk of death in freezing temperatures.
Solution: Move to a warmer location; use a heat mat for seedlings; cover plants in light frost.
Hot Stress
Leaf scorch, wilting, or reduced flowering; may drop leaves to conserve water.
Solution: Provide shade during peak heat; increase watering; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season; avoid fertilizing in winter.
